SASH-BALANCE.

T0 aZZ whom it may concern.-

Be it known that I, QUINCY BALDWIN, a citizen of the United States, residing at Tonganoxie, in the county of Leavenworth and State of Kansas, have invented certain new and useful Improvements in \Vindow-Sash Balances and Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The special object of the invention is to make a combined sash balanceand fastener, as hereinafter fully described, and then pointed out in the claim.

Figure I of the drawings is an elevation showing my invention when the window is closed, and Fig. 2 a longitudinal section showing it when the window is open at top and bottom. Fig. 3 is a detail perspective view of my clasp.

In the drawings, A represents a windowframe, in which slide two sashes, B 13, of equal weight.

0 is a cord or chain made fast at one end to the middle of the upper rail, 1), of the top sash, and then carried up over a pulley, D, arranged on the frame A, just above the point of the cord or chain fastening on top sash. Thence it falls to a point within easy reach of a grown persons uplifted hand. \Vhen either the top sash is pulled down or the lower sash pushed up, orboth at the same time, the cord or chain 0 is secured in a spring-clasp, E, arranged on the upper rail, The two sashes may I), of the lower sash.

thus be both balanced and locked. The clasp E has two elastic side pieces, 6 e, concaved on the under side to form a guide-channel for the sash-cord, and gradually approaching each other from the bottom toward the top, so as to make an intermediate upwardly-converging slot, 6. By this construction the cord 0 Will run freely in the guide-channel under the side pieces, 6 e, and yet may be easily fastened by an upward motion of the hand or unfastened by a downward motion thereof.

I am aware that it is not new to balance two sashes by a cord passing over a pulley or through an eye-piece on the upper part of window-frame, the lower end of cord being detachably fastened in some way; but I desire to claim as my invention only the particular construction of my sash-cord fastener. This enables me to do away with the ordinary means by which the sashes are balanced, all weights, sash-cords, and pulleys on the inside of window-frame, all defacement of the frame by notches, slots, excisions, spring-catches, dogs, and slide-bolts.

What I claim as new, and desire to protect by Letters Patent, is

In window-sash balances, the clasp E, having the two elastic side pieces, 6 6, meeting, or nearly so, at the top, forming a subjacent guide-channel for the cord C, and making an upwardly-taperin g intermediate slot, e,wl1ereby it maybe used in connection with the cord, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
